I don't know why creams would be the first line treatment. They trap moisture in the groin area! You want it to be as dry as possible. Personally I use anti-fungal powder. It works like a charm!

For me, it worked to increase personal hygiene. I washed the affected area twice daily with anti-fungal soap. I dried the area and applied cream containing clotrimazole. I also change shorts twice a day. keep area as dry as possible. Sleep naked.

I always get it toward the summer, however, after I visited the physician and found out what it is exactly, it's easy to prevent. The doctor prescribed antibiotics and topical creams, but now I always use antifungal soap as well as antifungal powder, and make sure to keep the area as dry as possible. I haven't had it for 3 years now.

In my case, I almost always get it towards the end of a long work day (I'm a landscaper). Jock itch is painful and makes finishing up a job the last thing I want to do. The solution: baby powder, lots, every morning!
